Oops! Making a T-Shirt quilt.

I've done t-shirt quilts and used flannel as backing, but I'd be afraid to use it for border strips. When you start sewing 2 types of material together they need to be at least distant cousins. :) Now, if you sew the t-shirts onto a piece of cotton to totally stabilize it, you can use the flannel as a border. I sew the t-shirts to cotton and use a temporary spray and make sure it's stuck well. The t-shirt material can be stretchy and tricky to work with.

I made my son a tee shirt quilt. I ironed on the Pellon thin iron on before cutting the sqs so it would not shift during cutting. Then I did it like a regular quilt..using the bars around each block. I posted it in projects, if you want to go see. I don't know how you can find my projects, but someone here can tell you, I'm sure! I used Kona cotton for both the bars & the backing, with warm & natural in the middle...then paid to have it quilted! There are several ways to do a tee shirt quilt, some easier than how I did. But you really should use that iron on to stablize the knit shirts. Good luck!
